. FILE-CLEANING IMPLEMENT.

' Specification of Letters Patent.

' .Pae'nama. a, 1917.

Application filed December as, 1915. Serial no. 69,113. I

To all whom it may concern Be it known that I, E RwI N D. MGIMIILLEN, a subject of the King of Great Britain,

residing at Omaha, Nebraska, have invented certain .new and vuseful Improvements in F iIe-Cleaning Implements, of which the folflowing is a specification.

This invention has relation to certain new and useful improvements in file cleaning implements, and has for its primary object, the provision of a deviceof this characterwhich may be readily adjusted for cleaningvarious formsof file.

The invention has for another object, the provision of adjustable blades having 'file cleaning teeth and means for supporting said blades in adjusted position. 7

I The invention has for a furtheriob'ject, the provision of a file cleaning implement of this characterwhich will be of such con struction that'the blades may be readily adjusted with respect to one another and retained in adjusted position duringuse of the device. 1 V,

A further object of the invention resides in the provision of a file cleaning implement of the above-stated character which will also include a brush adjustable in the blade carrying case and positioned atone end of the blades. r a

The invention hasofor astill further object the provision of an implement "of this character including blades having graduated teeth upon their vworkingedges, and means for separating the blades and retaining them in proper spaced relation for movement through the grooves ofa file or the like to clean the same.

With the above and other objects in view, thein-vention resides in the novel construction, combination, and arrangement of parts as hereinafter set forth in the'specification POlIltQClyOllt inuthe claims, and

shown inthe drawings, in which-.

The forward ends of the blades 3 are pro- 3 are provided with the graduatedfteeth 5,

the larger teeth being at the forward ends of the blades 3 and terminating a shortdis twice from the forward points 6 of said blades 3. Theteeth at the rear ends ofthe blades 3 are very small and resemble fine saw teeth. Thelower edges .of the blades 3 are beveled on oneside, preferably the left vided with outwardly inclinecl lower edges 4: andthe entire lower edges 4 of said blades side as shown vin Fig. 4, whi le the upper edges'ofsa id' blades 3 are beveled upon both sid e's,as shown clearly, in'Fig. 7 and designated .by the. numeral .7, the purpose of which will presently appear. k

I n W111 b understood am. the bottemof the easel isopen and the lower edges 'ofthe blades 3 project from the same. It will also be seen by referring to the drawing that a brush 8' is in the. rear end of the case 1,

bristles directly back of the bladesB, the of the brush projecting about the sameqdistance astthelower edges of the blades 3. The brush 8 is mounted upon the side, sup- Ipor'ting pins 9 which project througlrthe rearwardly inclined elongated guideslots 10 in the sides of the case. 1 and maybe readily adjusted by means of the adjusting screw 11 projecting through the rear end of the case 1- and having threaded engagement withthe top of body 12 of the brush 8, said adjusting screw 11 being provided with a suitable head 13. uponits outer end. It will be understood that the. bristles of the brush I V wires or of The supporting rods QeXtend thrOughthe forward and rearward portions of. the blades 3 and in. theuppe edges of the bladesrearwardly of the forward rod 2 I have provided the recesses 14 having curved bottom walls and verticalfront walls to proits vide the shoulders 15). I have also provided the blades 3 with the reversed slots 16 in their upper edges and forwardly of the rear rod 2, the slots 16 having curved lower walls and rear walls to provide the shoulders 17 in front of the rear rods 2. Above the blades 3 and above the recesses 1% and 16 1 have provided the forward and rear spacer carrying shafts 18. Upon the shafts 18 1 have mounted the blade spacers 19 having" the radial arms 20 with beveled side projections 21 to separate the blades 3 as the shafts 18 are rotated to bring the proper arms 20 to position between said blades 3 and thereby retain the same in proper spaced relation. Each spacer 19 is preferably'provided with three arms 20 differing in thickness and the spacers .are slidable on and rotatable with each shaft 19 with their corresponding arms 20 parallel. It will also be seen that each spacer 19 has flanged sections 22 between the arms 20 which engage between the shoulders 15 and 17 to prevent the blades 3 from moving too near the center of the rods 2 under influence of the tension springs 23 upon the opposite ends of said rods 2. It will also be seen that, while the arms 20 ar riding in the recesses 14 and 16 or above the blades 3, they will not serve to separate the blades 3, but, as the arms 20 move to position between the shoulders 15 and the shoulder 17 they will force the blades 3 to separate without danger of causing said blades 3 to bind upon the rods 2. The tension springs 2 1 mounted upon the opposite ends of the shafts 18 exert an inward pressure upon the spacers 19 and serve to limit outward movement of the spacers 19 and automatically return said spacers to normal position upon the shafts 18 as the arms 20 are moved from between the shoulders 15 and the shoulders 17 of said blades 3. The shafts 18 are also each provided with a suitable head 25 upon one end, exteriorly of the case 1, by means of which said shafts 18 may be readily rotated.

From the foregoing, it will be readily apparent that by rotation of the shafts 18, the blades 3 may be readily forced apart or per mitted to move "toward one another under influence of the springs 23 and thereby properly adjust the blades 3 with-respect to one another to permit said blades to ride in the grooves of a file, the graduated teeth 5 and the bristles of the brush 8 removing all foreign matter from said grooves and thoroughly cleaning the file without injury to the same. It will also be seen that this instrument may be employed for cleaning various forms of files.

While the preferred embodiments of the invention have been shown and described, it will be undestood that minor changes in the details of construction, and arrangement of parts may be'resorted to within the scope of the appended claims without departing radians from the spirit of the invention or sacrificing any of the advantages of the same.
